  • ActiveRecord validates... custom field name.

    - by Dmitriy Likhten
    I would like to fix up some error messages my site generates. Here is the problem: class Brand < ActiveRecord::Base validates_presence_of :foo ... end My goal is to make a message "Ticket description is required" instead of "Foo is required" or may not be blank, or whatever. The reason this is so important is because lets say previously the field was ticket_summary. That was great and the server was coded to use that, but now due to crazy-insane business analysts it has been determined that ticket_summary is a poor name, and should be ticket_description. Now I don't necessarily want to have my db be driven by the user requirements for field names, especially since they can change frequently without functionality changes. Is there a mechanism for providing this already?

  • How do I set the dimensions of a custom component defined in an ActionScript class?

    - by user339681
    I'm trying to set the height of a vertical bar (activityBar) but it does not appear to do anything. i have tried something similar with the whole component, but setting the dimensions does nothing (even in the mxml used to instantiate the class). Indeed, I've added transparent graphics just to give the component some dimensions I'm not sure what I'm doing wrong. It's something bad though; my approach seems dire. FYI: I'm trying to create a mic activity bar that will respond to the mic by simply setting the height of the activityBar child (which seems to me to be more efficient than redrawing the graphics each time). Thanks for your help! package components { import mx.core.UIComponent; public class MicActivityBar extends UIComponent { public var activityBar:UIComponent; // Constructor public function MicActivityBar() { super(); this.opaqueBackground = 0xcc4444; graphics.beginFill(0xcccccc, 0); graphics.drawRect(0,-15,5,30); graphics.endFill();// background for bar activityBar = new UIComponent(); activityBar.graphics.beginFill(0xcccccc, 0.8); activityBar.graphics.drawRect(0,-15,5,20); activityBar.graphics.endFill(); activityBar.height=10; addChild(activityBar); } } }

  • Any point in subclassing UIButton to create a custom looking button?

    - by glitch
    I want to create a set of buttons that would work and feel very much like the Metro-style tiles that are available on Windows Phones. I would like to allow the user to tap them to access their underlying functionality (open a modal or something or that sort). I'm concerned that subclassing UIButton will not get me there. I need square corners and dynamic content inside the tiles themselves. The posts I've found around SO seem to suggest that subclassing a UIButton would not be a good idea for several reasons and that I should instead use UIView. That reply is from 2010, and I have no idea if in the 2+ years since then there have been considerable changes to how one would achieve that effect. Most users these days will have iOS 5.1+ if not 6.0 soon. Let's say I do go the UIView route. Should I implement UIResponder's touch events or should I instead go the UITapGestureRecognizer route? What's the better practice in 2012? Thank you!

    - by Kareed
    I am trying to make a module to add a table to a form in another module. I found I can add the new data in a module_form_alter hook but how to I get it to run through a theme hook? The module I am trying to modify has a theme hook for the page I want to modify. I don't want to change the original form I just want to add a table with new data below it. Thanks

    - by pavun_cool
    Hi All.. Normally when I am writing the perl program . I used to include following package . use strict ; use warnings ; use Data::Dumper ; Now , I want like this, I will not include all this package for every program . for that I will have these all package in my own package. like following. my_packages.pm package my_packages ; { use strict ; use warnings ; use Data::Dumper; } 1; So, that if I add my_packages.pm in perl program , it needs have all above packages . Actually I have done this experimentation . But I am not able get this things . which means when I am using my_packages . I am not able get the functionality of "use strict, use warnings , use Data::Dumper ". Someone help me out of this problem.....

  • associate dhcp requests with subdomains in dnsmasq

    - by Dezra
    I have dnsmasq running as a dns server with a number of linux boxes using static ips that run several virtual hosts on subdomains. I currently have the following address line in my dnsmasq.conf to map the subdomain of a boxes address to the boxes static ip: address=/.devbox1.mydomain.com/192.168.1.3 address=/.devbox2.mydomain.com/192.168.1.4 e.g. site1.devbox1.mydomain.com > maps to devbox1 static ip, site1 virtual host site2.devbox1.mydomain.com > maps to devbox1 static ip, site2 virtual host site3.devbox2.mydomain.com > maps to devbox2 static ip, site3 virtual host I was wondering if I can change the machines over to DHCP addresses (instead of static) and have dnsmasq use the dhcp ip instead of the static one? Can I modify the address line to refer to the DHCP address (obviously, I cant hardcode the address)? I know I could add mac address to ip allocation, but I want to avoid this if possible.

  • Best way to handle PHP sessions across Apache vhost wildcard domains

    - by joshholat
    I'm currently running a site that allows users to use custom domains (i.e. so instead of mysite.com/myaccount, they could have myaccount.com). They just change the A record of their domain and we then use a wildcard vhost on Apache to catch the requests from the custom domains. The setup is basically as seen below. The first vhost catches the mysite.com/myaccount requests and the second would be used for myaccount.com. As you can see, they have the exact same path and php cookie_domain. I've noticed some weird behavior surrounding the line below "#The line below me". When active, the custom domains get a new session_id every page load (that isn't the same as the non-custom domain session). However, when I comment that line out, the user keeps the same session_id on each page load, but that session_id is not the same as the one they'd see on a non-custom domain site either despite being completely on the same server. There is a sort of "hack" workaround involving redirecting the user to mysite.com/myaccount, getting the session ID, redirecting back to myaccount.com, and then using that ID on the myaccount.com. But that can get kind of messy (i.e. if the user logs out of mysite.com/myaccount, how does myaccount.com know?). For what it's worth, I'm using a database to manage the sessions (i.e. so there's no issues with being on different servers, etc, but that's irrelevant since we only use one server to handle all requests currently anyways). I'm fairly certain it is related to some sort of CSRF browser protection thing, but shouldn't it be smart enough to know it's on the same server? Note: These are subdomains, they're separate domains entirely (but on the same server). <VirtualHost *:80> DocumentRoot "/opt/local/www/mysite.com" ServerName mysite.local ErrorLog "/opt/local/apache2/logs/mysite.com-error.log" CustomLog "/opt/local/apache2/logs/mysite.com-access.log" common <Directory "/opt/local/www/mysite.com"> AllowOverride All #php_value session.save_path "/opt/local/www/mysite.com/sessions" php_value session.cookie_domain "mysite.local" php_value auto_prepend_file "/opt/local/www/mysite.com/core.php" </Directory> </VirtualHost> #Wildcard (custom domain) vhost <VirtualHost *:80> DocumentRoot "/opt/local/www/mysite.com" ServerName default ServerAlias * ErrorLog "/opt/local/apache2/logs/mysite.com-error.log" CustomLog "/opt/local/apache2/logs/mysite.com-access.log" common <Directory "/opt/local/www/mysite.com"> AllowOverride All #php_value session.save_path "/opt/local/www/mysite.com/sessions" # The line below me php_value session.cookie_domain "mysite.local" php_value auto_prepend_file "/opt/local/www/mysite.com/core.php" </Directory> </VirtualHost>

  • hudson/jenkins: help needed to get started with customization work

    - by user64204
    I'm would to customize jenkins by adding links to the left hand side panel and use the pages associated with these links to serve some custom content in place of the jobs/views table displayed by default. I managed to add links to the side-bar using the sidebar-links plugin. Now I'm trying to see how to replace the content of the <td id="main-panel"> element with some custom content. The custom content is generated by some PHP scripts which ideally should be called by hudson every time the custom pages are requested, though if too complicated I can either create static content to be served by jenkins by calling my PHP scripts in a crontab or see if calls to the PHP scripts can be done by apache itself before the page requests are sent to jenkins. I'm not sure writing a plugin is the best way to proceed and I would like to have your thoughts as to how you think I should implement this.

  • How can I "filter" postfix-generated bounce messages?

    - by Flimzy
    We are using postfix 2.7 and custom SMTPD (based on qpsmtpd) in highly customized configuration for spam filtering. We have a new requirement to filter postfix-generated bounces through our custom qpsmtpd process (not so much for content filtering, but to process these bounces accordingly). Our current configuration looks (in part) like this: main.cf (only customizations shown): 2526 inet n - - - 0 cleanup pickup fifo n - - 60 1 pickup -o content_filter=smtp:127.0.0.2 Our smtpd injects messages to postfix on port 2526, by speaking directly to the cleanup daemon. And the custom pickup command instructs postfix to hand off all locally-generated mail (from cron, nagios, or other custom scripts) to our custom smtpd. The problem is that this configuration does not affect postfix generated bounce messages, since they do not go through the pickup daemon. I have tried adding the same content_filter option to the bounce daemon commands, but it does not seem to have any effect: bounce unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 defer unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 trace unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 For reference, here is my main.cf file, as well: biff = no # TLS parameters smtpd_tls_loglevel = 0 smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtp_tls_security_level = may mydestination = $myhostname alias_maps = proxy:pgsql:/etc/postfix/dc-aliases.cf transport_maps = proxy:pgsql:/etc/postfix/dc-transport.cf # This is enforced on incoming mail by QPSMTPD, so this is simply # the upper possible bound (also enforced in defaults.pl) message_size_limit = 262144000 mailbox_size_limit = 0 # We do our own message expiration, but if we set this to 0, then postfix # will try each mail delivery only once, so instead we set it to 100 days # (which is the max postfix seems to support) maximal_queue_lifetime = 100d hash_queue_depth = 1 hash_queue_names = deferred, defer, hold I also tried adding the internal_mail_filter_classes option to main.cf, but also tono affect: internal_mail_filter_classes = bounce,notify I am open to any suggestions, including handling our current content-filtering-loop in a different way. If it's not clear what I'm asking, please let me know, and I can try to clarify.

  • Windows Desktop Switchboard / Toolbar

    - by codex73
    I'm researching a way to provide a somewhat custom toolbox, widget or switchboard which will reside on users desktop visible at most times for easy access to resources. Resources could be websites, local computer applications, custom api, etc. Compatibility should be Windows XP, 2008 Server, 7, Vista. Unsure if I should custom build an application with Visual Studio, Customize a Open Source Package or what could be a good simple implementation. Any advice or comments on this will be greatly appreciated.

  • Achieving A 1600 x 900 Resolution For (Guest OS) Ubuntu Under (Host OS) Windows 7

    - by panamack
    I am running Ubuntu 11.10 as a guest OS using VirtualBox 4.1.16 installed on Windows 7 Ultimate. On my laptop I'd like to be able to run Ubuntu in full screen mode at 1600 x 900. I only have options within the virtual machine to select 4:3 display settings such as 1600 x 1200, 1440 x 1050 etc. I have guest additions installed. At the windows command prompt, I tried typing: VBoxManage setextradata "Virtual Ubuntu Coursera ESSAAS" "CustomVideoMode1" "1600x900x16" This didn't work, still no 1600 x 900 res available in Ubuntu. I tried this having read the following section of the VirtualBox help (this also says something about a 'video mode hint feature' not sure what this means): 9.7. Advanced display configuration 9.7.1. Custom VESA resolutions Apart from the standard VESA resolutions, the VirtualBox VESA BIOS allows you to add up to 16 custom video modes which will be reported to the guest operating system. When using Windows guests with the VirtualBox Guest Additions, a custom graphics driver will be used instead of the fallback VESA solution so this information does not apply. Additional video modes can be configured for each VM using the extra data facility. The extra data key is called CustomVideoMode with x being a number from 1 to 16. Please note that modes will be read from 1 until either the following number is not defined or 16 is reached. The following example adds a video mode that corresponds to the native display resolution of many notebook computers: VBoxManage setextradata "VM name" "CustomVideoMode1" "1400x1050x16" The VESA mode IDs for custom video modes start at 0x160. In order to use the above defined custom video mode, the following command line has be supplied to Linux: vga = 0x200 | 0x160 vga = 864 For guest operating systems with VirtualBox Guest Additions, a custom video mode can be set using the video mode hint feature. UPDATE 02.06.12 I've just tried creating a new virtual machine using the same original disk image I had been given. This had Guest Additions v 4.1.6 installed and provided me with the 1600 x 900 full screen display I want. It's after I then install Guest Additions v 4.1.16 (the version included with my VirtualBox installation) that my only choices are 4:3 displays e.g. 1600 x 1200. Seems this is the cause.

  • direct url to server ip address and port

    - by AM0
    We have a Windows 2012 dedicated server. There’s a custom service running on port xxxxx which accepts connections from our custom built hardware devices over TCP/IP port. As of now we use servername.serverdomain.com:xxxxx to connect to the service and start communication. However, we prefer to use URL instead of server’s name or IP Address. So we got a custom url and set its name servers to point to dedicated server. However, just setting DNS doesn’t seem to be working. Could someone please guide as to how to get it working? UPDATE In short I want www.custom-url.com being forwarded to servername.serverdomain.com:xxxxx. These requests are coming from hardware and not browser.

  • Visual Studio 2013 Static Code Analysis in depth: What? When and How?

    - by Hosam Kamel
    In this post I'll illustrate in details the following points What is static code analysis? When to use? Supported platforms Supported Visual Studio versions How to use Run Code Analysis Manually Run Code Analysis Automatically Run Code Analysis while check-in source code to TFS version control (TFSVC) Run Code Analysis as part of Team Build Understand the Code Analysis results & learn how to fix them Create your custom rule set Q & A References What is static Rule analysis? Static Code Analysis feature of Visual Studio performs static code analysis on code to help developers identify potential design, globalization, interoperability, performance, security, and a lot of other categories of potential problems according to Microsoft's rules that mainly targets best practices in writing code, and there is a large set of those rules included with Visual Studio grouped into different categorized targeting specific coding issues like security, design, Interoperability, globalizations and others. Static here means analyzing the source code without executing it and this type of analysis can be performed through automated tools (like Visual Studio 2013 Code Analysis Tool) or manually through Code Review which already supported in Visual Studio 2012 and 2013 (check Using Code Review to Improve Quality video on Channel9) There is also Dynamic analysis which performed on executing programs using software testing techniques such as Code Coverage for example. When to use? Running Code analysis tool at regular intervals during your development process can enhance the quality of your software, examines your code for a set of common defects and violations is always a good programming practice. Adding that Code analysis can also find defects in your code that are difficult to discover through testing allowing you to achieve first level quality gate for you application during development phase before you release it to the testing team. Supported platforms .NET Framework, native (C and C++) Database applications. Support Visual Studio versions All version of Visual Studio starting Visual Studio 2013 (except Visual Studio Test Professional) check Feature comparisons Create and modify a custom rule set required Visual Studio Premium or Ultimate. How to use? Code Analysis can be run manually at any time from within the Visual Studio IDE, or even setup to automatically run as part of a Team Build or check-in policy for Team Foundation Server. Run Code Analysis Manually To run code analysis manually on a project, on the Analyze menu, click Run Code Analysis on your project or simply right click on the project name on the Solution Explorer choose Run Code Analysis from the context menu Run Code Analysis Automatically To run code analysis each time that you build a project, you select Enable Code Analysis on Build on the project's Property Page Run Code Analysis while check-in source code to TFS version control (TFSVC) Team Foundation Version Control (TFVC) provides a way for organizations to enforce practices that lead to better code and more efficient group development through Check-in policies which are rules that are set at the team project level and enforced on developer computers before code is allowed to be checked in. (This is available only if you're using Team Foundation Server) Require permissions on Team Foundation Server: you must have the Edit project-level information permission set to Allow typically your account must be part of Project Administrators, Project Collection Administrators, for more information about Team Foundation permissions check http://msdn.microsoft.com/en-us/library/ms252587(v=vs.120).aspx In Team Explorer, right-click the team project name, point to Team Project Settings, and then click Source Control. In the Source Control dialog box, select the Check-in Policy tab. Click Add to create a new check-in policy. Double-click the existing Code Analysis item in the Policy Type list to change the policy. Check or Uncheck the policy option based on the configurations you need to perform as illustrated below: Enforce check-in to only contain files that are part of current solution: code analysis can run only on files specified in solution and project configuration files. This policy guarantees that all code that is part of a solution is analyzed. Enforce C/C++ Code Analysis (/analyze): Requires that all C or C++ projects be built with the /analyze compiler option to run code analysis before they can be checked in. Enforce Code Analysis for Managed Code: Requires that all managed projects run code analysis and build before they can be checked in. Check Code analysis rule set reference on MSDN What is Rule Set? Rule Set is a group of code analysis rules like the example below where Microsoft.Design is the rule set name where "Do not declare static members on generic types" is the code analysis rule Once you configured the Analysis rule the policy will be enabled for all the team member in this project whenever a team member check-in any source code to the TFSVC the policy section will highlight the Code Analysis policy as below TFS is a very extensible platform so you can simply implement your own custom Code Analysis Check-in policy, check this link for more details http://msdn.microsoft.com/en-us/library/dd492668.aspx but you have to be aware also about compatibility between different TFS versions check http://msdn.microsoft.com/en-us/library/bb907157.aspx Run Code Analysis as part of Team Build With Team Foundation Build (TFBuild), you can create and manage build processes that automatically compile and test your applications, and perform other important functions. Code Analysis can be enabled in the Build Definition file by selecting the correct value for the build process parameter "Perform Code Analysis" Once configure, Kick-off your build definition to queue a new build, Code Analysis will run as part of build workflow and you will be able to see code analysis warning as part of build report Understand the Code Analysis results & learn how to fix them Now after you went through Code Analysis configurations and the different ways of running it, we will go through the Code Analysis result how to understand them and how to resolve them. Code Analysis window in Visual Studio will show all the analysis results based on the rule sets you configured in the project file properties, let's dig deep into what each result item contains: 1 Check ID The unique identifier for the rule. CheckId and Category are used for in-source suppression of a warning.       2 Title The title of warning message       3 Description A description of the problem or suggested fix 4 File Name File name and the line of code number which violate the code analysis rule set 5 Category The code analysis category for this error 6 Warning /Error Depend on how you configure it in the rule set the default is Warning level 7 Action Copy: copy the warning information to the clipboard Create Work Item: If you're connected to Team Foundation Server you can create a work item most probably you may create a Task or Bug and assign it for a developer to fix certain code analysis warning Suppress Message: There are times when you might decide not to fix a code analysis warning. You might decide that resolving the warning requires too much recoding in relation to the probability that the issue will arise in any real-world implementation of your code. Or you might believe that the analysis that is used in the warning is inappropriate for the particular context. You can suppress individual warnings so that they no longer appear in the Code Analysis window. Two options available: In Source inserts a SuppressMessage attribute in the source file above the method that generated the warning. This makes the suppression more discoverable. In Suppression File adds a SuppressMessage attribute to the GlobalSuppressions.cs file of the project. This can make the management of suppressions easier. Note that the SuppressMessage attribute added to GlobalSuppression.cs also targets the method that generated the warning. It does not suppress the warning globally.       Visual Studio makes it very easy to fix Code analysis warning, all you have to do is clicking on the Check Id hyperlink if you are not aware how to fix the warring and you'll be directed to MSDN online or local copy based on the configuration you did while installing Visual Studio and you will find all the information about the warring including how to fix it. Create a Custom Code Analysis Rule Set The Microsoft standard rule sets provide groups of rules that are organized by function and depth. For example, the Microsoft Basic Design Guidelines Rules and the Microsoft Extended Design Guidelines Rules contain rules that focus on usability and maintainability issues, with added emphasis on naming rules in the Extended rule set, you can create and modify a custom rule set to meet specific project needs associated with code analysis.

  • Formatting Dates, Times and Numbers in ASP.NET

    Formatting is the process of converting a variable from its native type into a string representation. Anytime you display a DateTime or numeric variables in an ASP.NET page, you are formatting that variable from its native type into some sort of string representation. How a DateTime or numeric variable is formatted depends on the culture settings and the format string. Because dates and numeric values are formatted differently across cultures, the .NET Framework bases its formatting on the specified culture settings. By default, the formatting routines use the culture settings defined on the web server, but you can indicate that a particular culture be used anytime you format. In addition to the culture settings, formatting is also affected by a format string, which spells out the formatting details to apply. The .NET Framework contains a bounty of format strings. There are standard format strings, which are typically a single letter that applies detailed formatting logic. For example, the "C" format specifier will format a numeric type as a currency value; the "Y" format specifier displays the month name and four-digit year of the specified DateTime value. There are also custom format strings, which display a apply a very specific formatting rule. These custom format strings can be put together to build more intricate formats. For instance, the format string "dddd, MMMM d" displays the full day of the week name followed by a comma followed by the full name of the month followed by the day of the month. For more involved formatting scenarios, where neither the standard or custom format strings cut the mustard, you can always create your own formatting extension methods. This article explores the standard format strings for dates, times and numbers and includes a number of custom formatting methods I've created and use in my own projects. There's also a demo application you can download that lets you specify a culture and then shows you the output for the standard format strings for the selected culture. Read on to learn more!

  • New TFS Template Available - "Agile Dev in a Waterfall Environment"–GovDev

    - by Hosam Kamel
      Microsoft Team Foundation Server (TFS) 2010 is the collaboration platform at the core of Microsoft’s application lifecycle management solution. In addition to core features like source control, build automation and work-item tracking, TFS enables teams to align projects with industry processes such as Agile, Scrum and CMMi via the use of customable XML Process Templates. Since 2005, TFS has been a welcomed addition to the Microsoft developer tool line-up by Government Agencies of all sizes and missions. However, many government development teams consistently struggle with leveraging an iterative development process all while providing the structure, visibility and status reporting that is required by many Government, waterfall-centric, project methodologies. GovDev is an open source, TFS Process Template that combines the formality of CMMi/Waterfall with the flexibility of Agile/Iterative: The GovDev for TFS Accelerator also implements two new custom reports to support the customized process and provide the real-time visibility across the lifecycle with full traceability and drill down to tasks, tests and code: The TFS Accelerator contains: A custom TFS process template that implements a requirements centric, yet iterative process with extreme traceability throughout the lifecycle. A custom “Requirements Traceability Report” that provides a single view of traceability for the project.   Within the Traceability Report, you can also view live status indicators and “click-through” to the individual assets (even changesets). A custom report that focuses on “Contributions by Team Member” tracking things like “number of check-ins” and “Net lines added”.  Fully integrated documentation on the entire process and features.

  • MySQL - Installation

    - by Stuart Brierley
    In order to create a development environment for a project I am working on, I recently needed to install MySQL Server.  The first step was to download the msi. Running this presents you with the installer splash screen, detailing the version of MySQL that you are about to install - in this case MySQL Server 5.1. Next you can choose whether to install a Typical, Complete or Custom installation.  Although this is the first time I have installed MySQL and the Custom option states "Recommended for advanced users" I opted to carry out a Custom installation, specifically so that I could be sure of what features and components were installed. On the Custom Setup screen you can choose which components to install.  By default the Developer Components are not included, but I opted to include some of these elements. Next up is the ready to install screen and then the intsallation progress.   Following the completion of the installation you are shown a few screens with details of the MySQL Enterprise subscription option. Finally the installation is complete and you are offered the chance to configure and register MySQL. Next I will be looking at the configuration of MySQL Server 5.1.

  • Announcing: Great Improvements to Windows Azure Web Sites

    - by ScottGu
    I’m excited to announce some great improvements to the Windows Azure Web Sites capability we first introduced earlier this summer.  Today’s improvements include: a new low-cost shared mode scaling option, support for custom domains with shared and reserved mode web-sites using both CNAME and A-Records (the later enabling naked domains), continuous deployment support using both CodePlex and GitHub, and FastCGI extensibility.  All of these improvements are now live in production and available to start using immediately. New “Shared” Scaling Tier Windows Azure allows you to deploy and host up to 10 web-sites in a free, shared/multi-tenant hosting environment. You can start out developing and testing web sites at no cost using this free shared mode, and it supports the ability to run web sites that serve up to 165MB/day of content (5GB/month).  All of the capabilities we introduced in June with this free tier remain the same with today’s update. Starting with today’s release, you can now elastically scale up your web-site beyond this capability using a new low-cost “shared” option (which we are introducing today) as well as using a “reserved instance” option (which we’ve supported since June).  Scaling to either of these modes is easy.  Simply click on the “scale” tab of your web-site within the Windows Azure Portal, choose the scaling option you want to use with it, and then click the “save” button.  Changes take only seconds to apply and do not require any code to be changed, nor the app to be redeployed: Below are some more details on the new “shared” option, as well as the existing “reserved” option: Shared Mode With today’s release we are introducing a new low-cost “shared” scaling mode for Windows Azure Web Sites.  A web-site running in shared mode is deployed in a shared/multi-tenant hosting environment.  Unlike the free tier, though, a web-site in shared mode has no quotas/upper-limit around the amount of bandwidth it can serve.  The first 5 GB/month of bandwidth you serve with a shared web-site is free, and then you pay the standard “pay as you go” Windows Azure outbound bandwidth rate for outbound bandwidth above 5 GB. A web-site running in shared mode also now supports the ability to map multiple custom DNS domain names, using both CNAMEs and A-records, to it.  The new A-record support we are introducing with today’s release provides the ability for you to support “naked domains” with your web-sites (e.g. http://microsoft.com in addition to http://www.microsoft.com).  We will also in the future enable SNI based SSL as a built-in feature with shared mode web-sites (this functionality isn’t supported with today’s release – but will be coming later this year to both the shared and reserved tiers). You pay for a shared mode web-site using the standard “pay as you go” model that we support with other features of Windows Azure (meaning no up-front costs, and you pay only for the hours that the feature is enabled).  A web-site running in shared mode costs only 1.3 cents/hr during the preview (so on average $9.36/month). Reserved Instance Mode In addition to running sites in shared mode, we also support scaling them to run within a reserved instance mode.  When running in reserved instance mode your sites are guaranteed to run isolated within your own Small, Medium or Large VM (meaning no other customers run within it).  You can run any number of web-sites within a VM, and there are no quotas on CPU or memory limits. You can run your sites using either a single reserved instance VM, or scale up to have multiple instances of them (e.g. 2 medium sized VMs, etc).  Scaling up or down is easy – just select the “reserved” instance VM within the “scale” tab of the Windows Azure Portal, choose the VM size you want, the number of instances of it you want to run, and then click save.  Changes take effect in seconds: Unlike shared mode, there is no per-site cost when running in reserved mode.  Instead you pay only for the reserved instance VMs you use – and you can run any number of web-sites you want within them at no extra cost (e.g. you could run a single site within a reserved instance VM or 100 web-sites within it for the same cost).  Reserved instance VMs start at 8 cents/hr for a small reserved VM.  Elastic Scale-up/down Windows Azure Web Sites allows you to scale-up or down your capacity within seconds.  This allows you to deploy a site using the shared mode option to begin with, and then dynamically scale up to the reserved mode option only when you need to – without you having to change any code or redeploy your application. If your site traffic starts to drop off, you can scale back down the number of reserved instances you are using, or scale down to the shared mode tier – all within seconds and without having to change code, redeploy, or adjust DNS mappings.  You can also use the “Dashboard” view within the Windows Azure Portal to easily monitor your site’s load in real-time (it shows not only requests/sec and bandwidth but also stats like CPU and memory usage). Because of Windows Azure’s “pay as you go” pricing model, you only pay for the compute capacity you use in a given hour.  So if your site is running most of the month in shared mode (at 1.3 cents/hr), but there is a weekend when it gets really popular and you decide to scale it up into reserved mode to have it run in your own dedicated VM (at 8 cents/hr), you only have to pay the additional pennies/hr for the hours it is running in the reserved mode.  There is no upfront cost you need to pay to enable this, and once you scale back down to shared mode you return to the 1.3 cents/hr rate.  This makes it super flexible and cost effective. Improved Custom Domain Support Web sites running in either “shared” or “reserved” mode support the ability to associate custom host names to them (e.g. www.mysitename.com).  You can associate multiple custom domains to each Windows Azure Web Site.  With today’s release we are introducing support for A-Records (a big ask by many users). With the A-Record support, you can now associate ‘naked’ domains to your Windows Azure Web Sites – meaning instead of having to use www.mysitename.com you can instead just have mysitename.com (with no sub-name prefix).  Because you can map multiple domains to a single site, you can optionally enable both a www and naked domain for a site (and then use a URL rewrite rule/redirect to avoid SEO problems). We’ve also enhanced the UI for managing custom domains within the Windows Azure Portal as part of today’s release.  Clicking the “Manage Domains” button in the tray at the bottom of the portal now brings up custom UI that makes it easy to manage/configure them: As part of this update we’ve also made it significantly smoother/easier to validate ownership of custom domains, and made it easier to switch existing sites/domains to Windows Azure Web Sites with no downtime. Continuous Deployment Support with Git and CodePlex or GitHub One of the more popular features we released earlier this summer was support for publishing web sites directly to Windows Azure using source control systems like TFS and Git.  This provides a really powerful way to manage your application deployments using source control.  It is really easy to enable this from a website’s dashboard page: The TFS option we shipped earlier this summer provides a very rich continuous deployment solution that enables you to automate builds and run unit tests every time you check in your web-site, and then if they are successful automatically publish to Azure. With today’s release we are expanding our Git support to also enable continuous deployment scenarios and integrate with projects hosted on CodePlex and GitHub.  This support is enabled with all web-sites (including those using the “free” scaling mode). Starting today, when you choose the “Set up Git publishing” link on a website’s “Dashboard” page you’ll see two additional options show up when Git based publishing is enabled for the web-site: You can click on either the “Deploy from my CodePlex project” link or “Deploy from my GitHub project” link to walkthrough a simple workflow to configure a connection between your website and a source repository you host on CodePlex or GitHub.  Once this connection is established, CodePlex or GitHub will automatically notify Windows Azure every time a checkin occurs.  This will then cause Windows Azure to pull the source and compile/deploy the new version of your app automatically.  The below two videos walkthrough how easy this is to enable this workflow and deploy both an initial app and then make a change to it: Enabling Continuous Deployment with Windows Azure Websites and CodePlex (2 minutes) Enabling Continuous Deployment with Windows Azure Websites and GitHub (2 minutes) This approach enables a really clean continuous deployment workflow, and makes it much easier to support a team development environment using Git: Note: today’s release supports establishing connections with public GitHub/CodePlex repositories.  Support for private repositories will be enabled in a few weeks. Support for multiple branches Previously, we only supported deploying from the git ‘master’ branch.  Often, though, developers want to deploy from alternate branches (e.g. a staging or future branch). This is now a supported scenario – both with standalone git based projects, as well as ones linked to CodePlex or GitHub.  This enables a variety of useful scenarios.  For example, you can now have two web-sites - a “live” and “staging” version – both linked to the same repository on CodePlex or GitHub.  You can configure one of the web-sites to always pull whatever is in the master branch, and the other to pull what is in the staging branch.  This enables a really clean way to enable final testing of your site before it goes live. This 1 minute video demonstrates how to configure which branch to use with a web-site. Summary The above features are all now live in production and available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today.  Visit the Windows Azure Developer Center to learn more about how to build apps with it. We’ll have even more new features and enhancements coming in the weeks ahead – including support for the recent Windows Server 2012 and .NET 4.5 releases (we will enable new web and worker role images with Windows Server 2012 and .NET 4.5 next month).  Keep an eye out on my blog for details as these new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Sharing authentication methods across API and web app

    - by Snixtor
    I'm wanting to share an authentication implementation across a web application, and web API. The web application will be ASP.NET (mostly MVC 4), the API will be mostly ASP.NET WEB API, though I anticipate it will also have a few custom modules or handlers. I want to: Share as much authentication implementation between the app and API as possible. Have the web application behave like forms authentication (attractive log-in page, logout option, redirect to / from login page when a request requires authentication / authorisation). Have API callers use something closer to standard HTTP (401 - Unauthorized, not 302 - Redirect). Provide client and server side logout mechanisms that don't require a change of password (so HTTP basic is out, since clients typically cache their credentials). The way I'm thinking of implementing this is using plain old ASP.NET forms authentication for the web application, and pushing another module into the stack (much like MADAM - Mixed Authentication Disposition ASP.NET Module). This module will look for some HTTP header (implementation specific) which indicates "caller is API". If the header "caller is API" is set, then the service will respond differently than standard ASP.NET forms authentication, it will: 401 instead of 302 on a request lacking authentication. Look for username + pass in a custom "Login" HTTP header, and return a FormsAuthentication ticket in a custom "FormsAuth" header. Look for FormsAuthentication ticket in a custom "FormsAuth" header. My question(s) are: Is there a framework for ASP.NET that already covers this scenario? Are there any glaring holes in this proposed implementation? My primary fear is a security risk that I can't see, but I'm similarly concerned that there may be something about such an implementation that will make it overly restrictive or clumsy to work with.

  • How do I load tmx files with Slick2d?

    - by mbreen
    I just started using Slick2D and learned how simple it is to load in a tilemap and display it. I tried atleast a dozen different tmx files from numerous examples to see if it was the actual file that was corrupted. Everytime I get this error: Exception in thread "main" java.lang.RuntimeException: Resource not found: data/maps/desert.tmx at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoader.java:69) at org.newdawn.slick.tiled.TiledMap.<init>(TiledMap.java:101) at game.Game.init(Game.java:17) at game.Tunneler.initStatesList(Tunneler.java:37) at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:164) at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390) at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314) at game.Tunneler.main(Tunneler.java:29) Here is my Game class: package game; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.SlickException; import org.newdawn.slick.state.BasicGameState; import org.newdawn.slick.state.StateBasedGame; import org.newdawn.slick.tiled.TiledMap; public class Game extends BasicGameState{ private int stateID = -1; private TiledMap map = null; public Game(int stateID){ this.stateID = stateID; } public void init(GameContainer container, StateBasedGame game) throws SlickException{ map = new TiledMap("data/maps/desert.tmx","maps");//ERROR } public void render(GameContainer container, StateBasedGame game, Graphics g) throws SlickException{ //map.render(0,0); } public void update(GameContainer container, StateBasedGame game, int delta) throws SlickException{ } public int getID(){return stateID;} } I've tried to see if anyone else has had similar problems but haven't turned up anything. I am able to load other files, so I don't believe it's a compiler issue. My menu class can load images and display them just fine. Also, the filepath is correct. Please let me know if you have any pointers that might help me sort this out.

  • GIS-based data visualization and maintenance tool

    - by Dave Jarvis
    Background Looking to leverage an existing GIS system for exploring organizational data. Architecture The following figure represents a high-level overview of the system's desired features: The most basic usage would be as follows: The user visits a web site. The system presents a map (having regions, cities, and buildings). The user drills-down on the map to a particular building. The system provides a basic CRUD interface. The user can view and modify information about personnel (e.g., their assigned teams), equipment (e.g., network appliances), applications, and the building itself (e.g., contact and phone numbers). Ideally, all the components should be open-source (or otherwise free). Problem This must be a small project that needs a quick (but functional) prototype, mostly to confirm whether or not such a system would be useful in the long term. Questions What software components would you use to quickly develop a working prototype? What open-source solutions already exist, if any? Ideas Here is what I am thinking: PostGIS - Define the regions, cities, and sites Google Maps - Display an interactive, clickable map geoJSON - Protocol between PostGIS and Google Maps Seam - CRUD interface Custom Development For example, this would entail: Installation and configuration Configure SSH for remote logins Subversion (or git) PostgreSQL PostGIS Java Tomcat Seam JasperReports Enter GIS information into PostGIS Aggregate data sources into PostgreSQL database Develop starting page for map interface Develop clickable Google Maps interface Develop summary reports Develop CRUD interface using Seam for data maintenance Surely something like this already exists? Thank you!

  • Dynamic/Adaptive RLE

    - by Lucius
    So, I'm developing a 2D, tile based game and a map maker thingy - all in Java. The problem is that recently I've been having some memory issues when about 4 maps are loaded. Each one of these maps are composed of 128x128 tiles and have 4 layers (for details and stuff). I already spent a good amount of time searching for solutions and the best thing I found was run-length enconding (RLE). It seems easy enough to use with static data, but is there a way to use it with data that is constantly changing, without a big drop in performance? In my maps, supposing I'm compressing the columns, I would have 128 rows, each with some amount of data (hopefully less than it would be without RLE). Whenever I change a tile, that whole row would have to be checked and I'm affraid that would slow down too much the production (and I'm in a somewhat tight schedule). Well, worst case scenario I work on each map individually, and save them using RLE, but it would be really nice if I could avoind that. EDIT: What I'm currently using to store the data for the tiles is a 2D array of HashMaps that use the layer as key and store the id of the tile in that position - like this: private HashMap< Integer, Integer [][]
